HVT Testing will allow you identify the current combustion status of your boiler as close to the combustion zone as possible. The HVT probe accurately measures gas temperature, but also measures the different levels of gasses within the upper furnaces. The data collected during the HVT Test can determine:

• NOX and CO profiles

• Oxygen profile

• Oxygen levels

• Temperature profile

• Flue gas temperatures

• Possible fuel imbalances between burners

• Possible secondary air imbalances

• Possible air leakage into the boiler (leading to excessive O2 levels)
